Broadcast-Grade Single-Ear Headset Mic for Live Sound and Presentation

The DPA 4266 CORE+ Omnidirectional Flex Earset Microphone with 110mm boom and MicroLock connector is built for professional voice capture in presentations, broadcasting, and performance settings. Featuring DPA’s acclaimed 4066 capsule paired with the powerful CORE+ amplifier, this compact one-ear headset mic delivers exceptional speech clarity and natural tone in a lightweight, barely-there design. Its long boom arm ensures accurate placement for consistent vocal pickup, making it ideal for speakers, performers, and on-camera talent who need high-quality sound in a discreet form factor.

Flexible Fit with Lightweight Single-Ear Design for Discreet Use

This earset headset offers a comfortable, secure fit that adapts easily to a variety of ear sizes and head shapes. Its adjustable boom rotates to accommodate use on either the left or right side, while the slim, brown frame helps it blend into most skin tones for minimal visual distraction. With a medium-length 110mm boom arm, it positions the microphone capsule near the mouth for optimized voice pickup, ensuring consistent results whether used in theaters, corporate presentations, or live-streamed events.

MicroLock Connection Offers Secure Fit with Modular Compatibility

The 4266 uses DPA’s compact MicroLock connector, designed to reduce accidental disconnection and wear. Its locking design ensures stable performance throughout long hours of use on stage or in the studio. The modular nature of the MicroLock system means users can easily switch between different wireless transmitter adapters without replacing the mic—ideal for professionals who work across multiple setups. The system is also backward-compatible with MicroDot connectors for added versatility across equipment inventories.

Built-In CORE+ Amplifier Captures Clean Audio at High SPL Levels

DPA’s CORE+ amplifier technology enables this mic to handle sound pressure levels up to 134 dB RMS and 137 dB peak with less than 1% distortion. For louder applications, it can manage up to 144 dB SPL with minimal audio degradation. This makes it suitable for high-energy presentations, musical performances, and other dynamic vocal uses. The result is clean, intelligible sound even in louder environments, without clipping or artifacts that compromise audio quality.

Omnidirectional Capsule Delivers Natural, Consistent Voice Pickup

The omnidirectional pattern provides smooth, even response across the vocal range, regardless of the speaker’s movement or position. It captures sound equally from all directions, ensuring steady tonal quality even if the user turns their head. This is especially helpful in live scenarios where performers or presenters are in motion, offering natural speech reproduction without the need for constant mic adjustments.

Tone-Shaping Grids Help Tailor Sound to the Application

Two interchangeable boost grids are included for adjusting the high-end response of the microphone. The preinstalled Soft-Boost grid adds a subtle 3 dB boost from 8 to 20 kHz for enhanced vocal presence. The included High-Boost grid increases clarity further with a 10 dB bump around 12 kHz, perfect for cutting through noisy environments. Both stainless steel grids are scratch-resistant, durable, and easy to clean, providing long-lasting tonal flexibility.

IP58 Durability and Kevlar Cable Construction for Harsh Use

This headset is engineered to handle tough production environments. Its IP58 rating protects against dust and moisture, making it suitable for outdoor or high-activity use. The 4.1-foot cable is reinforced with Kevlar for added strength, offering resistance to bending, pulling, and repeated handling. Whether you're in a broadcast booth or on the move during a live show, this mic is built for the demands of everyday professional use.
